Motoyasu mentioned that their weapons could be tempered, but it required certain ores and the better quality of an ore the better return weapon would be, however Naofumi used the Prani Ore given to him by Rishia on the Shark Bite Shield so he did not have any more ore on hand to use to upgrade his Awakened Chimeric Viper Shield.
